Bosch MD1CS069 Gen2 — BSL / Bench

Bosch MD1CS069 Gen2 — BSL / Bench

BitBox adds BSL-mode unlocking, followed by bench operation, for locked Bosch MD1CS069 Gen2 control units from 2020 onwards, built on AURIX TC299 processors and fitted to diesel light commercial vehicles, trucks and industrial machinery, in its Bosch MG1/MD1 Gen2 BENCH module, SM2 and SM3 interfaces only. Note that the title says MD1CS069 while the body reads MG1CS069; the announcement does not explain the difference.

From the original announcement
« Support has been added for BSL-mode unlocking and subsequent bench operation with locked Bosch MG1CS069 Gen2 2020+ ECUs based on AURIX TC299 processors, used in diesel LCV, Trucks and Industrial vehicles, in the Bosch MG1/MD1 Gen2 BENCH [SM2/SM3 ONLY] module. »
